Yahoo! News - Gruesome Iraq Images Could Shake U.S. Opinion: "The images immediately evoked comparisons to the 1993 killings of 18 U.S. troops in Mogadishu, when crowds were filmed dragging the corpses of two U.S. soldiers through the streets. Washington ended its military presence in Somalia soon afterwards. "

In my opinion it was a big mistake to withdraw from Somalia after that attack (it wasn't a great idea to go there to begin with) and while I'm no fan of the war in Iraq it would be an even bigger mistake to withdraw from Iraq after this latest attack.

It's cliche to say "The terrorists win" but it's also true. If we let them chase us out by committing horrific acts of violence then we encourage them to use horrific acts of violence to get their way in the future.
